12.5. Obtaining Lucene

12.5.1. Problem

You need to use Lucene to create a searchable index of documents.

12.5.2. Solution

To use Lucene in a Maven 2 project, add the following dependency to your project's pom.xml:

Example 12.2. Adding a Dependency on Lucene

    <dependency>
        <groupId>org.apache.lucene</groupId>
        <artifactId>lucene-core</artifactId>
        <version>1.9.1</version>
    </dependency>

If you are not sure what this means, I'd suggest reading Maven: The Definitive Guide. When you depend on a library in Maven 2, all you need to do is add the dependency groupId, artifactId, and version to your project's dependencies. Once you do this, Maven 2 will download the dependency and make it available on your project's classpath.

12.5.3. Discussion

Lucene is a full-text search engine that can be used to index any information. Lucene maintains an index of Document objects that can contain any number of fields, and this index can be searched using a highly developed query language.
